Thank you for your question.
Unfortunately, it is impossible to predict what a prosecutor is likely to do or not do, because I do not have access to the file and do not know what others have said during the course of the investigation
. We have certain expectations based on what we know to be true, but we do not know whether those interviewed have told the truth.
We also do not know who the prosecutor believes.
Preservation of evidence is key. Off-site duplication is wise. To cover up, fib about, or try to hide that expensive gift from Aunt Sally last month just because you think it would be interpreted by a cynical prosecutor as being "really" bought with your "take" of the criminal
enterprise would be a grave mistake. One lie for ANY reason during and investigation makes you a liar forever in the eyes of these types of government servants.
Evidence of NO financial gain from the crimes can help a lot. It is smart to be ready to account for every penny spent since coming into contact with the accused. No increases in expenditures not precisely matching the legitimate income helps prove innocence.
An "accessory" charge requires evidence that the person accused actually *did* something to further the crime/crimes. For the best and most accurate accounting of your actions during the dangerous times, it is a good idea to think about any "favors" that either of the accused may have asked for--what they were, why, and in retrospect, whether that should have been a warning flag.
It is possible that you could be called to testify, but then again maybe not if the prosecution already has all they believe they need for a conviction. It sounds as if you would have little useful information anyway.
The other required element of the accessory or conspiracy
or similar assistance to criminals crimes is "intent". You describe a situation devoid of any criminal intent. That does not mean that one would not be accused, but it goes a long way towards either a not guilty verdict or a decision to drop the prosecution altogether.
